Solution phase reaction at ambient temperature of zinc nitrate, maleic acid and 4,4'-dipyridylamine (dpa) afforded {[Zn-2(maleate)(2)(dpa)(2)]center dot 5H(2)O}(n) (1), which displayed parallel (4,4)-grid like coordination polymer layers interdigitated into double layer slab motifs via hydrogen bonding. A similar reaction employing bis(4-pyridylmethyl)piperazine (bpmp) caused in situ cis-trans isomerization of maleic acid to fumarate, and generation of [Zn(fumarate)(bpmp)(H2O)(2)](n) (2). Compound 2 also manifested (4,4)-grid coordination polymer layers similar to those in 1; however, the larger apertures in 2 permit 2d + 2d -> 3D mutually inclined interpenetration. Thermogravimetric and luminescence studies are also reported for 1 and 2. (C) 2009 Elsevier B. V. All rights reserved.
